2. Description of the Related Art Most handy personal computers, handy word processors and the like have a keyboard in their main body and an openable / closable lid for covering the keyboard surface. Further, in order to make the device compact, many of the lids also serve as an LCD screen as a display. Due to its good function and portability, the handy personal computer or the like has been used in various ways other than by itself. That is, when connecting to an external printer and outputting the information stored in the main body as a hard copy, or when connecting an external keyboard and printer and using a handy personal computer only as the original computer main body. .

On the other hand, not only a handy personal computer but also many electronic devices use an LED to turn on / off the power, the presence / absence of a battery, etc.
A display device for emitting light using a small light source such as is provided, and the same applies to the above-mentioned handy personal computer and the like. That is, it is generally necessary to display "power on", "presence or absence of battery", "whether the floppy disk drive is operating", etc. on a handy computer. It is provided on the inner surface side of the body, that is, the display surface side. That is, it is desirable that the display device is located at the position most easily seen by the user while the user opens the lid and taps the keyboard to operate the display device. is there.

However, as the use of the handy personal computer spreads as described above, it may be used with the keyboard surface kept closed with the lid. Another display device is provided on the outer surface of the main body other than the keyboard surface or the outer surface of the lid body so that the operating state can be confirmed. Of course, the display contents (that is, "power on" or "battery exhausted") should be exactly the same for the display device inside the main body and the display device outside the main body, so they are turned on based on the same control circuit. However, recently, for the purpose of cost reduction, there is a device in which the same light source (LED) is used so that the light emitted from the light source appears on both the front and rear display devices of the lid. (For example, FIG. 6).

[0005]

[Problems to be Solved by the Invention]
In the conventional device shown in FIG. 1, one light source in the lid simply illuminates the light transmitting member (transparent plastic) flush with the lid exposed on the front and back surfaces of the lid, so that each light transmitting member shines. It is difficult to obtain contrast with the surrounding brightness, and when the external environment is bright, it is difficult to check whether the light emitting display on the lid surface is lit, especially when the lid is in use. there were. (In the use state with the lid upright, at least the hinge portion of the lid with respect to the main body becomes a little dark portion, so that it is easy to obtain contrast.) This invention solves the above problems with a simple configuration.

[0006]

A light emitting display device according to the present invention is a side surface of a lid body facing a support shaft pivotally supporting the body in a small electronic device such as the handy personal computer. Is provided with a light transmitting member whose surface is exposed toward the support shaft, a light emitting source is internally provided in the vicinity of the light transmitting member, and the light transmitting member is mounted on a bearing portion of the main body supporting the support shaft. The light reflecting surface is formed so as to reflect the light emitted from the member substantially forward and obliquely upward of the small electronic device.

[0007]

1 is a perspective view showing a state in which a lid (2) of a handy personal computer (1) according to the present invention is opened, and FIG. 3 is a perspective view showing the same in a closed state. This handy personal computer (1) comprises a main body (4) equipped with a keyboard (3) and a lid body (2) rotatably connected by a hinge part (5), and the back surface (inner surface) of the lid body (2). ) Is provided with an LCD plate (6) as a display. The hinge part (5) has three protrusions (4a) raised from the main body (4) and a lid (2).
Two protrusions (2a) provided on one side are engaged with each other, and a support shaft (7) is provided through them, and the upper portion of the protrusion (4a) is formed in a substantially semicircular shape. In this embodiment, the side of the lid (2) facing the hinge (5), more specifically, the valley between the two protrusions (2a) and the central protrusion (4a) of the main body. A light emitting display device (8) is provided throughout.

That is, as shown in the cross section of the light emitting display device (8) in FIG. 1, the casing (9) in the upper and lower halves forming the outer shape of the lid (2) is hollow.
The LCD plate (6) described above is fixed to the central portion, but the support shaft (7) is provided in the valley between the protrusions (2a) and (2a).
A slit-shaped small window (10) extending from a side surface facing to a part of the back surface (2b) of the lid is formed, and a substantially L-shaped transparent portion is formed such that the outer periphery is exposed from the small window (10). A lens (light transmitting member) (11) is provided. As shown in FIG. 2, the slit-shaped small window (10) and the transparent lens (11) are provided at six places side by side on the left and right sides of the lid.
The six transparent lenses (11) are integrally connected by an elongated lens plate (not shown) to form a lens assembly.

An LED (12) as a light emitting source is provided on the back surface of the transparent lens (11), and a portion (1) facing the support shaft (7) side of the transparent lens (11).
1a) is formed as a convex lens so that the light from the LED (12) is converged toward a reflecting mirror surface described later.

Next, the structure of the protrusion (4a) on the main body side will be described. The inside of the protrusion (4a) is also hollow as shown in FIG. 1, and a slit-shaped small window (13) is formed on the front side with the keyboard (3) surface. )
An approximately V-shaped second transparent lens (second light transmitting member) (14) is provided so that its outer periphery is exposed.
The slit-shaped small window (13) and the second transparent lens (14) are also arranged side by side on the left and right sides of the main body as shown in FIGS.
It is provided at a certain position, and the position thereof is a position that exactly faces the transparent lens (11) on the lid (2) side.

The inner surface of the substantially cylindrical casing (15) of the protrusion (4a) is aluminum-deposited according to the present invention to form a mirror surface (16) for reflecting light. A portion (14) of the second transparent lens (14) facing the LED (12) in the state shown by the solid line in FIG.
A) may be formed as a convex lens like the first transparent lens (11).

Since the handy personal computer (1) of this embodiment has the above-mentioned structure, the light emitted from the LED (12) is the first light when the lid (2) is opened (chain line in FIG. 1). The light enters the transparent lens (11) and causes the entire lens (11) to emit light, and in particular, the back surface (2) of the lid body of the lens (11).
The portion (11b) wrapping around to the side b) emits light in a relatively large area, and the lighting can be easily confirmed by the visual observation of the user (P).

When the cover (2) is closed (solid line in FIG. 1), the first lens (1) goes out from the LED (12).
The light converged through 1) passes through the second lens (14), is reflected by the mirror surface (16), and goes out above the forward slant around the eye position of the user (P) (Fig. 1 arrow (R)). At this time, the entire second lens (14) emits light and transmits the reflected light (R) satisfactorily to notify the user (P) of its lighting.

In the above embodiment, since the mirror surface (16) is formed on the substantially cylindrical portion of the protrusion (4a), the mirror surface (16) itself has a function of converging the reflected light (R). In another embodiment, an inclined flat surface portion may be formed in the protrusion (4a), and a mirror surface may be formed there by aluminum vapor deposition (FIG. 4). Further, in the above embodiment, the main body protrusion (4a)
Since the second transparent lens (14) is incorporated in the
When (12) emits light, the entire second lens (14) also emits light, and it is very easy to confirm lighting. However, in other embodiments, the second transparent lens (14) is omitted. Then, only the slit-shaped small window (13) is opened in the protrusion (4a) so that the light emitted from the first lens (11) directly hits the mirror surface (16) and goes out obliquely forward and upward. Good.

Further, as shown in FIG. 5, the mirror surface (16) in the protrusion (4a) has a mirror surface (16) having at least two angles.
a) (16b), a different mirror surface (1) not only when the lid body (2) is closed but also when the lid body (2) is opened.
The light may be reflected obliquely upward and upward by 6b).

[0016]

As described above, in the light emitting display device according to the present invention, it is possible to easily and accurately confirm whether or not the display is lit even if the external environment is bright. Moreover, the structure is simple in spite of the fact that two light emitting display positions can be easily illuminated by one light emitting source,
It can also be manufactured at a lower cost.
